XXI Olympic Winter Games 2010, Vancouver, Canada

The first Olympics after the war were held in Antwerp, Belgium and featured figure skating and ice hockey tournament. At the IOC Congress held the following year it was decided that the host nation of the 1924 Summer Olympics, France, would host a separate "International Winter Sports Week" under the patronage of the IOC. Chamonix was chosen to host this "week" (actually 11 days) of events. The Games proved to be a success when more than 250 athletes from 16 nations competed in 16 events. Athletes from Finland and Norway won 28 medals, more than the rest of the participating nations combined. In 1925 the IOC decided to create a separate Olympic Winter Games and the 1924 Games in Chamonix was retroactively designated as the first Winter Olympics.
St. Moritz, Switzerland, was appointed by the IOC to host the second Olympic Winter Games in 1928. Fluctuating weather conditions challenged the hosts. The opening ceremony was held in a blizzard while warm weather conditions plagued sporting events throughout the rest of the Games. Because of the weather the 10,000 metre speed-skating event had to be abandoned and officially cancelled. The weather was not the only note-worthy aspect of the 1928 Games; Sonja Henie of Norway made history when she won the figure skating competition at the age of 15. She became the youngest Olympic champion in history, a distinction she would hold for 74 years.
The next Winter Olympics was the first to be hosted outside of Europe. Seventeen nations and 252 athletes participated. This was less than in 1928 as the journey to Lake Placid, United States, was a long and expensive one for most competitors who had little money in the midst of the Great Depression. The athletes competed in fourteen events in four sports. Virtually no snow fell for two months before the Games, it was not until mid-January that there was enough snow to hold all the events. Sonja Henie defended her Olympic title and Eddie Eagan, who had been an Olympic champion in boxing in 1920, won the gold in the men's bobsleigh event to become the first, and so far only, Olympian to have won gold medals in both the Summer and Winter Olympics.
The German towns of Garmisch and Partenkirchen joined to organise the 1936 edition of the Winter Games, held on February 6–16. This would be the last time the Summer and Winter Olympics were held in the same country in the same year. Alpine skiing made its Olympic debut, but skiing teachers were barred from entering because they were considered to be professionals. Because of this decision the Swiss and Austrian skiers refused to compete at the Games.
